Hello,

In the last week or 10 days, I've been noticing an intermittent knock or grind for about a second while reversing slowly, and I'm wondering if anyone would have any experience with this. My vehicle is a 2008 C350 4MATIC - I changed the front discs and pads about a month and a half ago, I don't know if that has anything to do with it. Other than that, it runs and stops smoothly.

Thanks in advance!

I'd put the car on a lift(no load) to try and determine the location of the said noise!!

are you reversing straight back or while turning?

Thank you for your responses - it doesn't seem to matter whether I'm reversing straight or while turning and I've only noticed it when I don't press on the gas. Normally, I'll put the car in reverse and it'll start to slowly reverse without any gas. Last night, I was reversing out of a parking spot and about 2 seconds after the car started to move, it just stopped on its own, as if I pressed the brakes. I waited a few seconds to see if it would start moving again, but it's as if the brakes were applied. I had to give it some gas to get it moving again.

it doesn;t make any noise in drive

Nothing at all in drive, even under similar conditions (no gas, car at rolling speed on its own). Only ever happens intermittently when I reverse..

I'm having the same issues, it seems to be coming from the front drivers side.
